In this paper, the robust exponential $H_{infty }$ fault tolerant control problem is investigated, which is deus gorras concerned with uncertainties, disturbances and actuator failures.Determined by whether the actuator fails or not, the continuous-time system is remodeled as a switched system.Then a sampled-data controller is designed.Through Lyap
The influence of stirring click here speeds of 1000 and 1500 r/min on the microstructure of Al18SiCuMg alloy was investigated.The smaller size of Si particles of rheocast sample obtained by higher cooling rate and higher stirring speed was achieved.According to the results of cavitation test, the cavitation rate of the rheocast sample produced by 1
The coastal marine ecosystem near the Elwha River was altered by a massive sediment influx-over 10 million tonnes-during the staged three-year removal of two hydropower dams.We used time series of bathymetry, substrate grain size, remotely sensed turbidity, scuba dive surveys, and towed video observations collected before and during dam removal to
The intervertebral disc (IVD) is the fibrocartilaginous joint located between each vertebral body that confers flexibility and weight bearing capabilities to the spine.The IVD plays an important role in absorbing shock and stress applied to the spine, which helps to protect not only the vertebral bones, but also the brain and the rest of the centra
The urea cycle functions to incorporate ammonia, generated by normal metabolism, into urea.Urea cycle disorders (UCDs) are caused by loss of function in any of the enzymes responsible for ureagenesis, and are characterized by life-threatening episodes of acute metabolic decompensation with hyperammonemia (HA).A prospective analysis of interim HA ev
